The Cyclone series of fixed

and variable long pathlengthgas cells is the ultimate insampling accessories formeasuring the infrared spectraof gases and vapors.Designed for use at a widerange of temperatures andpressures, they are the idealchoice for the analyst whodemands superiorperformance characteristics,high standard specificationsand in-built upgradeability.

Based on the White cell principle of

multiple light passes between an

arrangement of reflecting mirrors,Cyclone gas cells are available in

three sizes:

Cyclone C2

Fixed or variable pathlengths ranging

from 0.5m to 2.5m

Cyclone C5


from 1m to 8m

Cyclone C10


from 2.1m to 10.6m

Cyclone series gas cells are suitable

for operation in all modern FT-IRspectrometers using the Specac

Benchmark baseplate provided as

standard.

Cells are available as standard with a

borosilicate glass body for operation at

ambient temperatures and pressures

ranging from vacuum to 15 p.s.i.

Protected gold mirrors, internal and

external components made from

nickel-plated aluminium and stainless

steel, and Viton O rings are combined

to ensure the highest chemicals

compatibility and protection from leaks.

Vacuum / gas inlet and outlet taps,KBr windows and a purgeable transfer

optics box further enhance this already

highly featured range.

Unsurpassed Upgradeability

Cyclones impressive list of optional

features means that any analytical

challenge can be met. Variable

pathlength mirror carriages, and a

range of fixed pathlength mirror

carriages can be used within a single

gas cell body to greatly enhance

analytical flexibility and reduce costs.

Nickel-plated aluminium bodies can be

specified for high pressure operation

up to 125 p.s.i., and heating jackets /

high stability temperature controllers

allow operation at temperatures up to

200C.

Purge bellows allow the transfer

optics to be used under inert gas

atmospheres (e.g. nitrogen) inapplications where the elimination

of atmospheric H2O and CO2

absorbances is required.

Design Excellence

To ensure perfect operation and

freedom from unwanted impurities,

a number of unique features have been

incorporated into the design and

manufacture of the Cyclone series.

The cells are completely free from

adhesives and all of the Viton O ring

seals are carefully pre-baked to

solvents or out-gassing. Internal

screws have small bleed holes drilled

into them to prevent any trapped

pockets of gas causing sample cross

contamination.

CE Compliance

All Cyclone series heated gas cell

systems are CE compliant ensuring

that they can be operated safely at

all times under the recommended

conditions.

Cyclone Series Gas Cells Optional Features

Cyclone series heatable long

pathlength gas cells have been

designed with the serious analyst

in mind. These high performance,

superior quality cells are backed

by a comprehensive range of

optional upgrades ensuring that

they meet every analytical

challenge.

Purge Bellows

A pair of purge bellows is available for the Cyclone

series gas cells. These fit between the optics box of

the cell and the spectrometer to allow the purging of

transfer optics with inert gases such as nitrogen. This

feature allows absorbances due to atmospheric H2O

and CO2to be eliminated from spectral measurements.

These bellows are designed to fit all Specac Bench-

mark sampling accessories.

GS10707 Purge Bellows (pair)

Heating Jacket / High Stability

Temperature Controller

All of the Cyclone series gas cells (glass and metal-

bodied versions) can be upgraded to heatable gas cells

by the addition of the appropriate Heating Jacket and

High Stability Temperature Controller. The heating jacket

simply slides over the gas cell and it can be operated

from ambient temperatures up to 200C.

Low voltage (30V) heaters are used to ensure safe

operation at all times and the temperature controller

can be fitted with an RS232, RS485 or USB interface to

allow independent control using a computer. Tempera-

ture stability is +/-1C and a key feature of the design is

the uniformity of the heating across the whole cell,

which prevents localised cold spots within the cell.

All of the Cyclone series Heating Jacket / High Stability

Temperature Controller systems are CE compliant

ensuring that they can be operated safely at all times

under the recommended conditions.

Cyclone Series Gas Cells Optional Features

Benchmark Series Laser

Alignment AccessoryThis accessory allows the visual verification of the

optical pathlength through Cyclone series gas cells.

This is especially useful when different pathlengths are

regularly used with variable pathlength cells.

The accessory is based on a low power (0.8mW)

visible continuous wave LED precisely located in

position in a Benchmark accessory alignment

housing. The gas cell simply slots into the alignment

accessory. The 635nm Class II laser can be powered

from a battery unit or by the dedicated mains

transformer supplied.

Benchmark Laser Alignment Accessory is CE

compliant ensuring that it can be operated safely at all

times under the recommended conditions.

GS24500 Benchmark Series Laser

Alignment Accessory

(Specify voltage and country).

Desiccant Storage Caps

These caps are designed to fit over the optical inlet

and outlet ports of the Cyclone

series gas cells toseal the transfer optics when the cells are not in use.

One of the caps contains a desiccant material which

maintains a dry atmosphere within the transfer optics

box and extends the life of KBr windows.

GS24150 Desiccant Storage Caps

Pressure Gauge Kit

A pressure gauge kit is available to fit the Cyclone

series gas cells. Gauges can be specified for low

pressure operation (vacuum to 15 p.s.i.) and high

pressure operation (vacuum to 125 p.s.i). An integral

pressure relief valve ensures that cells are

automatically depressurised in the event of accidental

over pressurisation.

Specac recommend the use of a pressure gauge

when operating gas cells at elevated pressures.
